Wiesemann and Theis

W&T (Wiesemann & Theis GmbH) connects serial, Ethernet, USB, PCI and IO


W&T develops its own products. This enables them to expertly address any problems that may occur in terms of the interoperability that they strive for.


W&T not only develop their own products, they also manufacture them themselves so that they are continuously monitored and improved. The results speak for themselves: more than 99.9% quality and reliability in 2015.


W&T document product characteristics as clearly and completely as possible; and answer your questions without delay.
They are also concerned with extreme long-term availability of our products: in their 25-year history, they have never had to phase out a single product.
